SOURCE: Cts wiper
Hi, disconect your battery positive cable for few minutes,reconect them back and see if this works ,(it should)if not ,play with the wiper swith back and foward,....good luck.....

SOURCE: My wiper blades stop working.
This sounds like the wiper motor. The brushes/commutators in the motor are probably fouling up. At high speed more current is sent to the motor so it works. If you replace the wiper motor this should solved the problem.
For the wiper pump check the fuse.
Then check to see if the fluid tube is clear and not plugged.
Finally check/clean electrical contacts on pump motor and if you can heard the wiper pump motor running when activated. If not replace pump motor. (they do wear out)
These parts can be gotten at auto recyclers also.

replace the wiper board, go to your local chevy dealer and purchase the wiper board. remove the wiper motor cover & you'll see the wiper board. be careful not to break to the plastic arm.

This solution applies specifically to a 91 Ranger with delay wipers, but may apply to other years as well:
There is a "cold solder" joint on the wiper control module that should be investigated whenever intermittent wiper issues crop up. I dont have the ability to post a schematic, but it is one of the leads that come off of the main terminal, and is fairly large. The solder around the lead will look dull and will most likely show physical separation from the circuit board itself. Re-solder with a good hot iron and it may well cure what ails ya. Takes 30-45 minutes, depending on how adept you are at worming your way under the dash to retrieve the module. It's to the left of the ashtray about 6 inches.

Body control module (BCM)
Wiper PCB relay
Wiper high PCB relay
Windshield wiper motor
Windshield washer fluid pump
Windshield washer fluid level switch
WPR fuse 25 A
WSW fuse 10 A
Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through the switch internal resistor and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WIPER PCB relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WIPER PCB relay and out to the switch input side of the WIPER HIGH PCB relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
High Speed Operation When the wiper switch is in the high speed position, ground is applied through the windshield wiper switch high signal circuit to the body control module (BCM) indicating the wiper high speed request. In response to this signal, the BCM then energizes the wiper PCB relay, as stated above, and the wiper high PCB relay by applying ground through the control circuit to the coil side of the relay. With the wiper high relay energized and its switch contacts closed to the high speed control circuit of the wiper motor, the motor will operate at high speed.
Wiper motor high speed operation and the wiper high speed PCB relay can also be commanded ON/OFF by using a scan tool. Refer to Control Module References.

You could Have a switch problem , BCM problem ,PCB relay problem , the pcb relays are non serviceable an the whole under hood fuse box would need to be replaced . Malfunctioning motor bad ground some where etc.....

The Crankshaft Position (CKP) Sensor is a permanent magnet output coil device that monitors the speed and position of the crankshaft. A reluctor is attached directly to the crankshaft, and is used to generate a constant signal as it passes the CKP sensor magnetic coil. The CKP Sensor utilizes system voltage (12 volts DC), or reference voltage (5 volts DC) to generate a digital output signal to the PCM that is based upon a 0.5 volt AC reference. The alternating magnetic field is used by the sensor output electronics to produce a digital pulse. The CKP sensor returns a digital ON/OFF signal pulse during each revolution of the crankshaft, with a momentary signal interrupt for the top dead center (TDC) position of the #1 cylinder. The Pulse Width Modulation pattern is used by the Powertrain Control Module (PCM) to calculate ignition timing, fuel injector timing, misfire diagnostics, and the tachometer display
